<h1 id="sstatelang/Contents">Steady-state file language</h1>


<p>Steady-state (sstate) files are a complementary tool to solve and analyse the steady states of more complex models. They allow you to create steady-state files independent of the original model files, and write the steady-state equations in different ways, manipulate their structure or order, split the problem into subblocks, and combine numerical and symbolic solutions. Using then the <a href="../sstatelang/Contents.html">sstate objects</a>, you can compile and run stand-alone steady-state m-file functions based on your steady-state files.</p>
